The means for manipulating the heel blank B relative to the cutter' 19,during the'shap' ing operation, includes a carrier arm which` isswingable horizontally by virtue of being fixed to a vertical axis'26.AThis axis 26 is supported in integral bearings 27, 28-`of a slide 31,which its avertical guide groove y32,

in the frame 17 of the machine, and said slide is adjustable up and downby means of a hand -screw 33,1rotatable in a lateral projection 34 ofthe machine.v frame 17 and engaging the v -lower bearing 28, see'Figs.I. and II. Bolts 29,A passing through slots in the slide r31, serve as aconvenient means for securing the latter in adjusted positions..Fastenedto .an

integral pad 36, at the vtop of the carrier arm feo 25, is a plate 37formed with an apertured boss 38 which is fixed to the axis 26 at theupper end, and which rests upon the topl of the bearing 27, as best seeninvFig. II. The carrier plate 37 is thus Virtually made a part vofthecarrier bracket 25 kand is therefore obligedto'move with it and theslide 31 during adjustment ofthe latter, as above noted. To facilitatesuch adjustment, the slide 31l is provided with an index 39^forco-ordinationv with graduations 40 along one edge of the sli de groove32, see Fig. II. l'Ihe carrier plate 37 also has a lateral extensionv 41equipped with ahandle 42 by which it may be Amanually lswung about theaxis 26 for a purpose'later on explained., the inward movementbeinglimited by a stop 43 secured by means of bolts 44 to the machine frame17, see Figs. II and III. At its top, the carrierl plate 37 ispro-Vvided with a guideway 45 to receive a carriage 46 which may beadjustably set along said'guideway in accordance with. graduations shownat 45m, Fig. III, by means of *clamp bolts '47 i passing throughelongated slots 48 in said plate. As shown in Fig. I, the carriage 46provides a bearing 50 that supports a .shaft 51, with capacity for bothrocking and axial movementyat an- Ainclinationr 'substantially parallelto the loweredges 203/, 213/ of the cutter blades 20, 21, said shaftcarrying at its outer end an'actuatingmember 52 equipped with a handle53. The actu'- .n

ating memberv 52 .is keyedV to the obliquely supported rock shaft 51at55, and is retained Vlimited through co-operation of a pin 58, 0n

tions -by a clamp bolt 62 and carries a roller. V63 that runs against aVplate 64 fastened to the carriage 46.` From Figs. II and VIII it willbe observed that the plate 64 has ar cam depression 65 Vadapted" tofbevovertravelled by the roller 63 with impartation of axial slidingmovement to the shaft 51, for a purpose also set forthhereinafter. Atits inner end, the inclined shaft 51 has a head 66 which, as shown inFig. IgV,lis reduced in thickness as at 67,' with: provision of atongueto fit between the side cheeks 68 of a member 69 constituting'partof a means 70 by which the heel blanks B are sustainedfand manipulatedrelativel tothe cutter 19 during shaping. Bolt and slot connections at71, 72, respectively, enablefadjustment of the member 69 relative tothehead 66, graduations 73--Fig;l I-being provided as an aid to this end.Side play between the head 66 and the member 69 is pre-- ventedthrough:rabbetedY engagement of a guideblock 74, securedin the" intervalkbetweentheside cheeks 68, with the inner end ofthe tongue 67, see Fig.IV. The means 70 further embodies upper and. lower holder jaws 76,respectively, that gripthe hee'l blanks B, atthe topxand bottom, in themanner shownin Fig. I. The lower aw 76 comprises a vsector 77-Fig.VI-which engages between ears78-Figs. I and IV-projecting forwardly fromthe lower part ofthe member 69, and it is pivotally supported by apintle v7S). The sector 77 is thus swingable on thepintle 7 9 forangular adjustment of the j aw7 6 relative to the shaft 51, inaccordance with graduations shown at 80 in Figs. I and VI,.while it is.clampable in adjusted positions by a bolt 81 passing through an arcuateslot 82 in the jaw sector piece 77. 'Io the i,

upper straight edge of the sector 77 is secured a face plate 83 having`teeth adapted tofirmly gripthebottom of the blank B, and a centrallongitudinal ridge 84-K-Fig. VII-,to lit the aligning groove G in thekbottom face fof said f Aheel blank.Y Asbest shown in Fig. VI, theforwardedge of the face plate 83 abuts against an upstanding lug 85 atthe frontal. portion of the sector 77, while it is secured in placejointly by dowel pins 86 and a screw 87. The upperclampin'g jaw 7 5-Fig,I- comprises AVa piece 88 in the form of a lever whichV is pivoted onastud bolt 89 passing, with capacityfor up and down adjustment to suitthe height of the blanks B, through slots i 90 in the `side cheeks 68ofthe member 69, said slots being located in vertical parallel-v ismvwith the Vaxisof the cutter 19. I To insure vagainst displacement ofthe b'olt89 in adj ust- .ed positions along the slots 90, one of thesidecheeksGS-of the member 69-is finely serrated transversely, as at 91, forco-0pera- Ation with the correspondingly corrugated face of a nut 92associated with said bolt, see Fig. V. A bushing 93 surrounding the bolt89 within the interval between the cheeks 68 of the member 69, acts as aspacer to prevent binding of the upper jaw 75 as the nut 92 is drawn uptight. As shown in Figs. I and IX the upper aw 75 is equipped with atoothed face plate 94 similar to that of the lower jaw 76, said platebeing adjustably secured by means of abolt 95 which passes through alongitudinal. slot and taking into the piece 88. The upper jaw 75 issubject to the upward pull of a tension spring 96 connected to aV keyUrooved screw bolt 97 which slidable endwise in an aperture in the topof the member 69 but kept from turning by means of a key, and equippedwith a spring "tension regulating nut 98. A'hand screw 99 taking into athreaded aperture in the overhanging portion 100, of the member 69,bears at its lower end upon an anti-friction ball 101 seated inadepression in the top edge of the upper jaw 75. l y i In employing themachine to shape the heel II of Fig. XII the procedure is as followsINhile the handle 53 of actuating member 52 j is in dotted position MFig. II, the carrier plate 37 with its appendages is bodily swung, bvmeans of handle 42, about its axis 26 away from the cutter 19 intodotted position-as shown in Fig. III-whereby access is afforded to thejaws 75, 76. The hand screw 99 is then backed off to relieve the uppergripping jaw 75 which is at the same time raised automatically throughinfluence of the tension spring 96, so that a heel blank B can beslipped into place on the lower gripping 7 6, with its groove Grengaging the tongue 84 of the toothed face plate 83, and its forward endabutting Vthe projection 85. The upper jaw 75 is thereupon depressed, bymeans of the hand screw 99, into firm sure contact with the top o'f theheel blank B, whereby the latter is tightly Agripped between the teethof the jaw facings 83, 94. The handle 53 is then swung from position Mto the right into the dotted position N, and while in this position, thehandle 42 is grasped and carrier plate 37 with its appendagesV swunginwarc about its aXis 26 against abutmentv43. The heel blank B is thuspassed in a tilted position under the cutter 19 into a tilted positionto the right of the same in readiness to be shaped. While holding thecarrier plate V37 Virmly against the abutment 43, the handle -'s movedfrom the dotted position N to theV left into the dotted position M Fig.II,

whereby the heel blank B is gradually swung through an are crosswise ofthe rotating profile cutter 19 with the result that anangular cut ismade in saidV blank to the depth shown in Fig. I. Now incident to thearcuate movequired.

presv ent of the heel blank B relative to the cutter 19 about the centerof the shaft 51 as an axis, it will be apparent that the breast shank S-Fig. XII, formed as a result of the angular cutting, will be roundedconveXly as at It by the edges 20% 21?/ of the cutter blades 20 and 21,while fthe inner face of the heel proper will be concurrently concavedas at() by the edges 20.70.l 2100` through concurrent axial shifting ofthe shaft 51, as predetermined by the configuration of the cam recess inthe plate 64 along which Vthe roller 63 on the actuating member 52travels. "I`hus by a single sweep of tie heel blank B crosswise of therotary cutter 19, I am able to effect an angularcut whereof the twosurfaces are .oppositely vcurved and merge smoothly into one another sothat no subsequent finishing is re- In this connection, it will beparticularly remarked that the comparatively deep concavity C at the topof the inner heel Pes reason that the axis of theshaft 51 of the heelblank holder 70 is tilted at an angle, as shown inFig.I. I

With regard to the adjustments provided for, it will be observed thatthe setting of the lower gripping jaw 76 about the pintle 79 v willAdetermine the angular relation of the surface B 'with respect to theplane of the to the cutting edges 203/, 213/ respectively. Shifting` ofthe holder 70, relative to the supporting head 66, determinesthe radiusof surface R; lowering or raising of slide 31, by means of hand screw33, determines thethickneSs of heel shank S; and shifting of theycarriage 46, toward or away from .the cutter19, determines the depth ofangularcut A. By means of these several adjustments together with theadjustable clamping jaw 75, and its independent adjustabletoothed faceplate 94 to accommodate clamping of heel blanks B of different height,the machine can obvious` ly be adapted to cutting'heels I-I of allsizes, with differently shaped breast Shanks.

The .heel I-I, illustrated in Fig. XIII, is identical with the heel I-Iof FigjXII-except that itsinner face C is substantially flat `instead ofbeing concaved. To produce the heel H-of Fig. XIII-with'the machine ofFigs. I, II and III, I simply remove the cam plate 61'and the roller 63,and, during the swinging of the holder 70 about the axis of the shaft 51by means of the handle 53, apply sutlieient pressure thereagainstmanually to prevent will be observed as generally similar in con- Vas tothe addition of the subscript L.

By virtue of the straight cutting of theinner heelfacein the present connection, axial shifting of the holder 70a becomesunnecessary, so that the roller 63 and co-operative cam plate Gli-ofFigs. I and VIII-are here omitted, While Ythe shaft 51a is sethorizontally in the bearing 50a of the carriage 49a instead of obliquelyas before. The manner of operating the machine of Fig. X is exactly thesame as described in connection with the first embodiment .as regardsplacement of a heel blank B in the holder 70a and manipulation of thecarrier plate 37a against abutment stop 43a in first positioning theblank B relative to the cutter 19a Vand afterwards causingV it to beswung crosswise through an arc about the shaft 51a,

as a center, to determine the angular cut and to effect ,concurrentconvexing of the breast shank. The various adjustment features foradapting the machine to fashioning heels of different sizes, etc.,areall retained in the modication as will be readily manifest fromexamination of Fig. X. To avoid rough edges in the finished heelsH or H,the outer rounding is done afterfasliioning of the anguiar bights A inraccordance with my invention, lwith the aid of other machinery and in amanner commonly practiced in this art.

While I have described my invention specifically iii connection withfashioning of shoe heels H, H', it is to be understood that the saine isadaptable to carrying'out other analogous shaping operations through-obviou's modifications all within the scope of the appended claims. fMoreover, by differently shaping the cam plate 64 it will be apparentthat many modifications are possible with re- Agard'to the shaping ofthe inner face C or C of the heel proper.
